astraxan [27]
H(t)=-16t^2+1221 is the function for the height as a function of time.  It will hit the ground when h=0 so:

-16t^2+1221=0

16t^2-1221=0

16t^2=1221

t^2=1221/16

t=√(1221/16) seconds

t≈8.74 seconds  (to nearest hundredth of a second)

A student finds the slope of the line between (8, 17) and (1, 4). She write 17-4/1-8. What mistake did she make?
Alex_Xolod [135]

Answer: OPTION D.

Step-by-step explanation:

The formula that is used to calculate the slope of a line is:

m=\frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) and (x_2,y_2) are two points on the line.

In this case the student finds the slope of the line that passes trough these points:

(8, 17)\\(1, 4)

You can notice that she writes in the numerator that:

y_2=17\\y_1=4

So she chose the point (1, 4) as (x_1,y_1)  and the point (8, 17) as (x_2,y_2).

Then x_2 and x_1 in the denominator must be:

x_2=8\\x_1=1

Therefore, she did not keep the order of the points the same in the numerator and the denominator.
